Quantum 'Compass' Promises Navigation Say Goodbye To GPS
Today our methods for pinpointing locations on Earth are dependent on space-based satellite navigation system, for example, the Global Positioning System (GPS)  but it's extremely fragile if a satellite fails or there's a jamming attack, it rapidly ends up useless. 

British boffins have built up an independent and carefully designed compass that doesn't depend on GPS signals to provide an exceedingly exact measure of where it is in the world. 

The compass is a quantum accelerometer. The device utilizes lasers to cool particles to greatly low temperatures, and after that estimates the quantum wave properties of those atoms as they react to acceleration. 

The system has been designed by boffins at Imperial College, London – who built up a laser system for cooling atoms off – and at photonics and quantum technology specialist M Squared - which built up another laser system to go about as an "optical ruler." Their work has been supported by the UK's Ministry of Defense. 

GPS, although one of the extraordinary innovations of the cutting edge age, has various constraints.Most notably, it depends on satellites being launched into space.And the US has beforehand cautioned that the system is at limit and could be defenseless against attack. 

A phone's GPS accurate to about 15 feet, although military GPS devices can be precise to centimeters. At that point there is the way that tall buildings will regularly throw a signal off and signal can be disabled by any huge, thick object. 

Quantum 'compass' isn't prepared to replace the accelerometer in your phone. It's solitary truly prepared for ships, trains and other huge vehicles where size and power requirements aren't major factors. It could keep transportation networks murmuring regardless of whether GPS fails outright.
